This vector data layer is a background of the major water bodies that fall within the US basemap data layer and are distributed with the Long Island Sound ArcView project file.

Purpose:

The purpose of this data layer is to provide a general reference as to major river systems that fall within the US basemap data layer as distributed with the Long Island Sound ArcView project file.

Although this derived data set and its lineage dataset have been used by the USGS, no warranty, expressed or implied, is made by the USGS or ESRI as to the accuracy of the data and/or related materials. The act of distribution shall not constitute any such warranty, and no responsibility is assumed by the USGS or ESRI in the use of these data or related materials.

The data is organized on five CD-ROMS. CD#1 contains data for the world, Mexico, Canada, Europe and the United States. Detailed data for the entire United States is continued on CD #2. The very detailed data for the regions of the United States is split between the west (CD #3), the east (CD # 4), and the south (CD #5). Also, there is a ssample image data on CD #5.

The ArcView shapefile, mjwater.shp, provided by ESRI with their software distribution was used to create the mjwater data layer for use with the Long Island Sound study project views.

Process_Step:

Process_Description:

The dataset was reprojected to the Clarke 1866 spheroid to be compatible with the other data layers.
